2.3 Wiring Connections

The subwoofer supports both high-level (speaker wire) and low-level (RCA) inputs. Choose the input method compatible with your car stereo/radio. Refer to your car stereo's owner's manual for details on radio wiring.

1. Power Connection: Connect the 12V Power Cable to the vehicle's battery (positive terminal). Ensure the inline fuse is properly installed.
2. Ground Connection: Connect the GND cable to a clean, unpainted metal surface on the vehicle's chassis.
3. Remote Turn-On: Connect the REM (remote) cable to the remote turn-on output of your car stereo. If your stereo does not have a remote output, you may use an accessory wire that turns on with the ignition.
4. Audio Input:
   • Low-Level Input (RCA): Connect RCA cables from your car stereo's RCA pre-outs to the subwoofer's RCA input jacks.
   • High-Level Input: If your stereo lacks RCA outputs, use the provided High to Low Level Converter. Connect your car stereo's speaker outputs to the converter, then connect the converter's output to the subwoofer's high-level input.
5. Remote Control: Plug the wired bass volume remote control into the designated port on the subwoofer.

3. Operating Instructions

Once installed, the subwoofer can be adjusted to achieve desired bass output.

3.1 Control Panel Adjustments

• PHASE (0°/180°): Adjusts the phase of the subwoofer output relative to the main speakers. Experiment with both settings to find the one that provides the most cohesive bass response.
• LOW PASS (50Hz - 150Hz): This filter controls the upper frequency limit of the subwoofer. Adjust it to blend the subwoofer's output smoothly with your main speakers. A lower setting (e.g., 80Hz) is common for larger main speakers, while a higher setting might be used with smaller speakers.
• BASS BOOST (0 - 12dB @ 45Hz): Increases the bass output at 45Hz. Use sparingly to avoid distortion.
• INPUT GAIN (MIN/MAX): Matches the subwoofer's input sensitivity to the output level of your car stereo. Start at minimum and slowly increase until you hear clear, undistorted bass.
• REMOTE CONTROL: Use the wired remote to conveniently adjust the bass volume from your driving position.

3.2 LED Indicator

The subwoofer features a green power LED and a red protection LED. The blue ambient LED light ring illuminates when the subwoofer is powered on, adding a visual element to your car's interior.

• Green LED: Indicates the subwoofer is powered on and operating normally.
• Red LED: Indicates a protection mode has been activated (e.g., thermal, short circuit, overload). Refer to the Troubleshooting section if this light illuminates.
• Blue Ambient LED: Illuminates when the unit is powered on. This feature is designed to be dynamic and cool.
